Brief sketch of how it works ?<br>
<br>
&nbsp;Each creature has a machine. <br>
<br>
&nbsp;INPUTS to machine are&nbsp; <br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp; - is there food to eat here ?<br>
&nbsp;&nbsp;&nbsp;&nbsp; - how hungry am I.<br>
<br>
&nbsp;OUTPUTS are<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp; - Move up,left,right,down ?<br>
&nbsp;&nbsp;&nbsp;&nbsp; - Eat.<br>
&nbsp;&nbsp;&nbsp;&nbsp; - Clone.<br>
<br>
&nbsp;<br>
&nbsp; machine is built from basic building blocks<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp; e.g. AND block&nbsp; . . .&nbsp; if INPUT 1
and INPUT 2 then set OUTPUT 3<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
OR&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
or<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp; feedback within machine allows complex
behavior to evolve. <br>
<br>
<br>
Future work.<br>
<br>
&nbsp;Investigate growth and developement. Multicell organisms start
life<br>
as a single cell. During development cells specialise to form<br>
different features. The specialisation is believed to be controlled by<br>
the realise of chemicals. Building this type of thing into simulations<br>
would be interesting. <br>
<br>
<br>
Notes:<br>
<br>
&nbsp;Code is written in JAVA. Could be emmbeded into HTML and used via
the<br>
internet. Various parameters can be changed and the effect observed. <br>
